Microwave Smart Sensor "BSS20"
Counter-terrorism measures for important infrastructure such as power plants and airports! The 3D radio wave wall reliably captures terrorists.
The "BSS20" is an intrusion detection sensor that uses radio waves in the 24GHz band. It detects intruders by blocking a detection area composed of multiple opposing transmitters and receivers. It is highly resistant to outdoor natural environments, easy to adjust during installation, and can be utilized as a counter-terrorism measure for critical infrastructure such as power plants and airports. 【Features】 ■ Strong against weather conditions such as rain, wind, snow, and fog, ensuring high reliability ■ No need for precise optical axis alignment like infrared sensors ■ Can be installed along walls, on top of fences, and in various locations ■ Forms a 3D radio wave barrier with up to 4 levels of multi-layer installation *For more details, please refer to the PDF materials or feel free to contact us.

Normal detection is possible even in heavy snowfall areas! "Snow Accumulation Prevention Cover (PSP-SCV)" and "Snow Accumulation Prevention Reflector (PRF-300SP)"
This time, we would like to introduce the "Snow Accumulation Prevention Cover (PSP-SCV)" and the "Snow Accumulation Prevention Reflector (PRF-300SP)." When snow accumulates on the surface of a microwave sensor, it may not be able to detect properly depending on the amount of snow. To prepare for such situations, we have the "Snow Accumulation Prevention Cover (PSP-SCV)" available. *Applicable sensors: BSS01, BSS20, BLS01, BFS01 By attaching this to the sensor, you can prevent snow accumulation on the sensor body. Additionally, when installing the microwave intrusion detection sensor (BSS01) facing the reflector, we also have the "Snow Accumulation Prevention Reflector (PRF-300SP)" designed to prevent snow accumulation on the reflector. By using these products together, normal detection is possible even in heavy snowfall areas.

Beam reflection detection method and beam interruption detection method, two detection methods of microwave.
At Pal Giken, we are developing various sensors that use "microwaves," and this time we will explain how they detect intrusions. ◆◆ Two Detection Methods ◆◆ Our microwave sensors support two detection methods. 1) Beam Reflection Detection Method A single sensor is installed, and the transmitted wave output from it defines the detection area. The detection range depends on the antenna angle of the sensor, but the sensor alone covers a wide distance. When a target intercepts the transmitted wave from the sensor, it is received as a reflected wave and detected as an "intrusion." 2) Beam Interruption Method This method configures the detection area by positioning the sensor and reflector opposite each other. The transmitted wave output from the sensor hits the reflector and is received as a reflected wave. There are also products that configure the detection area using a transmitter and receiver. In this case, the transmitted wave output from the transmitter is received by the receiver. In both cases, the levels that serve as the basis for transmission and reception are monitored, and if the wave is interrupted due to an intrusion, causing the level to fall below a threshold, it is detected as an "intrusion."

What is a microwave?
Microwaves are a type of radio wave and a form of electromagnetic wave. Electromagnetic waves propagate as repeating waves, and the number of repetitions per second is called frequency (measured in hertz, Hz). The length from the peak of one wave to the peak of the next is called wavelength. The name of electromagnetic waves changes according to their frequency, and their applications also vary based on their characteristics. In our company, we refer to radio waves with frequencies ranging from 3 GHz to 30 GHz (wavelengths from 10 cm to 1 cm) as "microwaves," and we use 24 GHz band radio waves in our microwave sensors. ◆◆ Features of Microwaves ◆◆ The features of microwaves include: - High directivity - Resistance to weather changes such as rain, fog, and snowfall - Ability to penetrate materials like resin, making them unaffected by obstacles These features, combined with our unique algorithms (signal processing technology), enable long-distance detection even in harsh environments. Additionally, our sensors can be used without a license. They can be used both indoors and outdoors in Japan, allowing for installation in various situations.
